I started with the Resmed Swift FX. I decided to try the Circadiance Sleepweaver elan because the Swift caused pain at the bottom of my nostrils, above my upper lip and my upper front teeth. I could have loosened it but sacraficed excessive leakage, and my wife sleeping elsewhere because of the air hissing noise.
The elan was a pleasant surprise. I wore it for two nights. There is some leakage and noise but no nostril, upper lip and upper teeth discomfort. My wife is beside me when I wake up.
I'm happy to sacrifice a little leakage and noise for comfort. I can, according to Circadiance, minimize leakage into my eyes (which I don't mind and feels nice with the cool humidified air) by positioning the sleepweaver feather weight hose over my head and using the headgear tether strap. This is recommended for lower pressure settings such as mine which is arond 7 as the elan needs to maintain a certain level of inflation to maintain its seal. I tried the tether with the hose over the headboard but rolling around from tummy to side to side got me in a tangled mess. Tether strap with hose over my head may work better after I get and install the hose buddy from supplier 1. I'll update after hose buddy arrives if I see interest in this review and/or my post.
Why only 3 stars? Circadiance doesn't make a small size so people like me with a small face don't have to wear a mask where the top is very close tp the bottom of the eyes and the mask bottom almost slides into the mouth.
Circadiance acknowledges that a smaller mask cushion is a possibility. Bring it on Circadiance. More customers will try the elan as I did. My review woud otrherwise be 4 stars.
I would have given Circadiance 4 stars for their Sleepweaver elan had it not been for thier refund guarantee. It's horrible for those outside the US or not shure we can obtain it, try it and return it within the period covered by the refund guarantee. You may read my post for more info.
Lastly, here's my weakness and here's where Circadiance shines. I cannot look at drawings and decipher what they mean. I need a conceptual explanation or a video that shows me step by step. Circadience video fills the bill. Mind you, I had to watch it numerous times to ensure that the headgear and mask was positioned correctly before I attempted to assembole them. It was much easier to follow than the Resmed Swift FX video.
